so that's what that was for

On my way through the Osco parking lot a week ago, I encountered three fire trucks, a horse trailer, and a score of underaged can-can dancers. The parking lot was otherwise empty. Strange...

Turns out they were there to celebrate the 150th anniversary of Somerville High School. But I think the real celebration has been the decoration of a "Slow Children" sign on our street with the commentary "because they're stoned".
